After installing Ubuntu 12.10 on this computer, I installed NVIDIA's proprietary driver, since I might want to play a few games. I soon started having problems with video and audio. I'd be watching a YouTube video, and it'd frequently “stutter”, that is, repeat the last few seconds of audio or skip a few seconds. The same happened while listening to some music, from either Rhythmbox or Banshee.

I booted up Ubuntu 13.04 from a USB stick and noticed that video and audio ran smoothly. I then attributed that to improvements to packages since version 12.10, and installed 13.04 on the machine instead. I installed the nvidia-current package right after booting into the system, and problems persisted. nvidia-current-upgrades, nvidia-experimental and other packages had the same problem.

I then thought that my problems could be related to the driver in use, since the LiveCD uses nouveau. I then replaced nvidia-current by nouveau and voilà, everything works just fine.

My question is: is there any tweaking required in order to get the proprietary driver running smoothly with the GeForce 8600M GT? I want to be able to play games and NVIDIA's driver has better 3D accelaration support, from what I've read.

Hi rberaldo, please read: askubuntu.com/questions/61396/… –  Luis Alvarado Apr 21 '13 at 3:39
    
@LuisAlvarado thanks for commenting. That page is pretty comprehensive but it unfortunately doesn't have any information on what I'm asking, I'm afraid. Installing drivers or understanding the difference between the proprietary driver and nouveau isn't a problem for me. I just can't get my mind around that nouveau is performing better than NVIDIA's driver, or understand why audio is affected. –  rberaldo Apr 21 '13 at 4:01
    
but did you at least try installing the PPA mentioned there and testing with that, specially for your case (8600M GT). For the performance of Nouveau I am actually happy seeing it win in cases like this. –  Luis Alvarado Apr 21 '13 at 4:13
    
Yes, I did try installing the drivers from the PPAs mentioned. The result was the same as with the stock drivers. It's pretty cool that the laptop is completely usable with nouveau, though. –  rberaldo Apr 21 '13 at 6:13
    
Can you please provide the laptop model. That might help figuring out what is wrong. –  Luis Alvarado Apr 21 '13 at 15:49
